I need to borrow a word from across the pond to describe my reaction to this book: 'Gobsmacked.'
Quite simply, Monte Cook has changed the d20 system in ways I didn't think were possible. This is an entirely new vision of what roleplaying is and what it could be.
Old familiar (and worn-out) ideas like alignment, race, and class are turned on their heads in this book. If you are looking for something other than the usual cookie-cutter d20 product, buy this book.
